Abstract: 27,803. National Cash Register Co., [National Cash Register Co.]. Dec. 18. Receipts, checking and recording; counting-apparatus.-In a cash register having registering, indicating, and printing mechanism for the transactions set up by a series of setting- elements, the registering-mechanism is actuated by an operating handle or lever controlled by the setting-elements, and the indicating-mechanism is moved from one position to another without being returned to zero. The register is shown in front elevation in Fig. 1, in end elevation in Fig. 3, and in vertical section in Fig. 5. Fig. 11 shows the counter. When an amount key 1 is depressed, it engages a pivoted lever 3 and forces it rearward to an extent equal to the key value. The lever 3 is pivoted to the rack-bar 4, which is forced to engage in the return stroke with the rack 5 upon the oscillating segment 6. The segment 6 operates the sliding rack 7 which has teeth 8 to operate the counter 9 when the counter is drawn down over the rack. The rack 7 through the pivoted lever 10 and the rack-bar 11 actuates the rotary indicator 12. The sliding and apertured detent plates 21 for locking the key shanks are elevated to release the depressed keys by means of a link bar reciprocated by a cam on the shaft 40<a>. This link bar is provided with a stud which moves into the path of a lug mounted on the shaft 40<a> to prevent manipulation of the machine by partially depressing a key. When the shaft 40 is rotated, two pivoted levers which support the transverse shaft 34 between their forward ends are rocked and the racks 4 are brought into mesh with the segment 5. The segments 6 are returned to their normal positions by the returning bar 57 through linkage and cam gearing. After the bars 7 have been set for an amount to be registered, indicated, and printed, they are locked by the pawls 65 which are set or released by the frame 69 rocked by a box cam mounted upon the shaft 40. Upon the initial movement of the crank handle, both cams 85, 86 are moved free of the roller 13 so that the lever 10 can move freely. When the bar 7 is elevated after a new registration, the roller 13 is elevated and the pin 78 becomes the fulcrum of the lever 10. The cam 85 or 86 forces the roller 13 to its normal locked position, and the bar 11 is moved to adjust its indicator. The indicating- mechanism is arranged to indicate the character of the transaction, a clerk's mark, and the amount of the transaction to both sides of the machine. Guard or flash plates 44 for the indicators are worked by linkages. The counter comprises the registering-wheels 103 mounted in a movable frame which is given a definite movement or excursion every time the crank is operated. The counter is first thrown forward, then the wheels are turned by the rack teeth, and is afterwards thrown out of gear and returned. During the return, the transfer from one wheel to another takes place. Each segment 6 is formed with rack teeth 47 to operate the printing-mechanism by gearing with the pinions 167. The pinions 167 are mounted upon sleeves 168 on the rock shaft 169 for the type wheels 14. The upper printing line of the type wheels is used for printing upon the detail strip, while the lower printing line is for the printing of the check. The devices for feeding the detail and check strips and for cutting off the check are controlled from the rotation shaft 40. The type wheels are unlocked after an impression has been made by withdrawing the pawl 159<a> from the toothed disc 168<a>, the cam disc 177 passing free of the pin 178. The check-printing mechanism may be thrown into and out of operative connection with the operating - mechanism by the means shown in Fig. 4. The coupling bolt 189 is mounted transversely to the sleeve, and projects laterally into engagement with the annular cap 190 on the printer frame. The bolt pin 192 extends into the slot 193 in the spring-pressed operating plate 194. When the shaft 181 and the sleeve are to be uncoupled, the stud 200 is forced inwards, and, when the sleeve is drawn outwards, the operation of the printing-cylinder ceases and the feeding of the check strip is stopped. The platen roller 218 is mounted upon the lever 219 which is oscillated twice upon each operation of the machine. In the main operating gear, the parts are locked when in their normal position, and to unlock them the handle 237 is forced slightly to the rear. To lock the operating-mechanism until a clerk's key has been depressed, the keyboard is provided with a pivoted lever located below the inner ends of the key-shanks.
